Lync Server PSTN Connectivity

We wish to introduce enterprise voice and dial-in conferencing in our Lync 2013 environment. Neither are currently configured. We are seeking a qualified resource with experience working with Lync Server 2013. We have a hybrid Lync deployment that consists of: 1. Skype for Business Online 2. Lync Server 2013 Front End (CORP-2012-LYNC1) 3. Lync Server 2013 Edge (CORP-2012-EDGE1) 4. Server 2012 ARR Reverse Proxy (CORP-2012-RP1) 5. Anynode Session Border Controller (CORP-2012-SBG1) The scope of this project is: 1. Configure Lync to utilize the Anynode SBC for PSTN connectivity. 2. Configure dial-in conferencing to utilize a DID delivered via SIP through the SBC. 3. Configure two users to make and receive calls via PSTN. 4. Place a test call from each user to the PSTN. 5. Receive a call from the PSTN to each user. Additional configuration in the Anynode SBC may be necessary. Support is available through the vendor. Connectivity will be available through VPN connectivity. The scope of this project must be completed in its entirety. While we are willing to deposit 100% of the project as a milestone payment, no payment will be authorized until 100% of the work has been completed.
